Create a method that group calls

[darius279]

As a admin, I want to optimize the mirror calls

Context

Description

We could add a method that validates those three things and thus save us the same call 4 times. Although as we call the mirror node, which does not generate an extra expense of gas or hbar, it could be done later.

Acceptance criteria

• I can create a stable coin succesffully
• I can cash in 100 tokens
• I can burn tokens
• I can wipe tokens
